I stored my photo library on an external SSD drive and after synching I'm getting an error
I'm a happy user of photos and excited with the new shared library feature. I still want to have a local copy on an external SSD drive so I create a system photo library on an external drive. It was formatted with Mac OS Extended (Journaled). The size is about 600 GB as I want all the photos and videos in their original size. I closed the photos app which took probably 30-45 minutes before I could eject the drive (I did force eject). After a few hours I connected the drive again and opened the photos app and got the following message
The library could not be opened.
Photos was unable to open the library “Name of the Photo Library.photoslibrary”. (4302)
Any thoughts?
